Description

Известны приборы дл  определени  модул  упругости текстильных нитей, включающие зажимы дл  нитей, записывающий осциллограф, генератор коротких импульсов и промежуточный усилитель.Instruments are known for determining the elastic modulus of textile yarns, including clamps for yarns, a recording oscilloscope, a short pulse generator, and an intermediate amplifier.

Описываемый прибор обеспечивает определение скорости распространени  упругой деформации по нити. Дл  этого его верхний и нижний зажимы, предназначенные дл  закреплени  предварительно нат нутой нити, смонтированы на двух расположенных одна над другой консольных балочках; кажда  балочка снабжена пьезоэлектрическим датчиком, включенным в цепь записывающего осциллографа, при этом к датчику верхнего зажима подключен генератор коротких импульсов, а между датчиком нижнего зажима и осциллографом включен промежуточный усилитель импульсов, снимаемых с нижнего датчика.The described device provides a determination of the rate of propagation of elastic deformation along a thread. To do this, its upper and lower clamps, designed to secure the preloaded yarn, are mounted on two cantilever beams placed one above the other; Each beam is equipped with a piezoelectric sensor included in a recording oscilloscope circuit, a short pulse generator is connected to the upper clamp sensor, and an intermediate pulse amplifier is removed from the lower sensor between the lower clamp sensor and the oscilloscope.

На фиг. 1 схематически изображен описываемый прибор. На-консольных балочках закреплены пьезоэлектрические датчики 1, 2 i зажимы 3 н 4, между которыми зажата предварительно нат нута  грузом 5 нить 6.FIG. 1 shows schematically the described device. On-cantilever beams, piezoelectric sensors 1, 2 i are fastened with clamps 3 and 4, between which a thread 5 is clamped pre-tensioned with a load 5.

Датчик 1 соединен с генератором 7 коротких импульсов и осциллографом 8, к которому через усилитель 9 подсоединен датчик 2.Sensor 1 is connected to a short pulse generator 7 and an oscilloscope 8, to which sensor 2 is connected through amplifier 9.

Дл  определени  скорости распространени  упругой деформации испытуемую нить 6 помещают между зажимами 3 vi 4, св занными с пьезоэлектрическими датчиками 1 и 2. Генератор 7 коротких импульсов подает импульс на датчик } и одновременно на осциллограф 8.To determine the rate of propagation of elastic deformation, the test string 6 is placed between clips 3 vi 4 connected to piezoelectric sensors 1 and 2. A short pulse generator 7 delivers a pulse to the sensor} and simultaneously to the oscilloscope 8.

На фиг. 2 изображена пленка, на которой пик а отмечает момент подачи импульса на датчик /. Электрический импульс преобразуетс  в датчике / в колебание, которое в виде упругой волны передаетс  нит м. Достигнув датчика 2, это колебание преобразуетс  в электрический импульс , который через усилитель 9 поступает в осциллограф 8, и на пленке отражаетс  пик б, отмечающий момент подхода упругой волны к датчику 2. По рассто нию между пиками о и б и по записи времениFIG. 2 shows a film on which the peak a marks the moment at which the pulse is applied to the sensor /. The electrical impulse is converted into a sensor / oscillation, which is transmitted in the form of an elastic wave to nit. After reaching sensor 2, this oscillation is converted into an electrical impulse, which through amplifier 9 enters the oscilloscope 8, and the film reflects the peak b, which marks the moment of the elastic wave approach to sensor 2. By distance between peaks a and b and by recording time
